Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 83/338,61/721
To find the GCF of fractions, we have to find the GCF of numerator numbers and LCM of denominator numbers. Its formula is given by
GCF of Fraction = Greatest Common Factor of Numerator/Least Common Multiple of Denominators
In the fractions 83/338,61/721, numerators are 83,61
Denominators are 338,721
The GCF of 83,61 is 1 .
LCM of 338,721 is 243698.
The greatest common factor of 83/338,61/721 = [GCF of 83,61]/[LCM of 338,721]= 1/243698
Therefore, the GCF of 83/338,61/721 is 1/243698.
To find the highest common factor of 83,61, we have to find the factors of both numbers and list the highest common factor.
The factors of 83 are 1, 83
The factors of 61 are 1, 61
The HCF of 83,61 is 1.
Lets's calculate GCF of 83,61
∴ So GCF of numbers is 1 because of no common factors present between them.
Lets's calculate LCM of 338,721
Given numbers has no common factors except 1. So, there LCM is their product i.e 243698
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/243698
Therefore, the GCF of Fractions 83/338,61/721 is 1/243698
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 338,721 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(338,721) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(338,721) x common factors =1 x 1 = 1
LCM(338,721) = ( 338 × 721 ) / 1
LCM(338,721) = 243698 / 1
LCM(338,721) = 243698
